`Be it known that I, Clientes W'. liinnnir,v

ya citizen of theUnited. States, residing" at Memphis, in the countyoffShelby and lState 5 of Tennessee, liavejinvented',certain new and useful Improvements in Spring-Wheels, which thefollowin'g'isaspecification This inventionrelates totspringfwheelsloff 3 Athat type having extensible spokes cushioned l by` coiledsprings, the spokes` being .formedff of two members and pivotally Iconnected at;

the opposite ends vto theihub andthe rim re` speetively. y l t v The object of-the inventioniis'to form an improved device of `the kind as will more fully appear hereinafter. l

` -The invention is'illustrate'd in theaccoinpanying drawingsin `wl iicli- Figure 1 is an elevation y and halfjsection of the wheel;` Fig. 2 is a section on the line 2-2 of -Fig. 1; Figs. 3 and 4 aresectional views of modified forms of spokes.

The invention is .applicable to `wheels-for railway cars, street cars, automobiles and other vehicles, land referring s ecifically `:t0

the drawings, 6 indicates a liu preferably cast or made of one piece of'nietal and pirovided with two peripheral spaced flanges 7 between `which the inner ends'of` the spokesIV -3() fit, the spokes being `pivotally rconnectedby means of cross bolts I8. .i Eachl spoke coniprises two parts, an-outerpiv plunger pa vrt, 9"

andan inner or tubular part 10. The latter is provided the flanges 7 to whichfit is-connected by the cross pins or bolts 8,' and the spaces between;

the heads of the spokes 'maybe lled with "cotton waste 12 orothercoinpressible :sub`l y40 l stance in order Ato excludedirt and r'noisfiure and provi de suiiicient lubrication. if desired. The plunger 9j is pivotally connected at-its outer end to thfi'ii-l by a cross bolt 14 1, the e rim being channeled and the "ends oithe spokes set in the Achannel4 between the flanges.

The inner end of ,the plunger 9iits` at a working litl inthe outer end of' the tube 10, and 'at the outer extremity the tube is ro'-v vided with an outwardly extending abou der l or flange 15.' Said tube is also slotted lengthwise as indicated at16, on oppositefsides, for

a portion of its length.` Afpin 1,57 extends t rough theinnerend of the plunger 9 and t l ough the slots, and car-ries a ring 18 which ts 'around or incloses thentube 1D, forming a'shoulder opposite `the `flange 15,.` inner tube 1o,v y plunger 'betweeiif the outery end of the tube4 andthe iriin, and springs 2l and 22 are coiled f5 areundfthe tube, on the outside, the former plate 24.

at the p inner end with' a` boled; aped head! 11 which fits betw een` -at'lvantages in cident t. coiled spring k19 is located between the inner end lofthe vilungerandthe inner end 'of the spring 20y is coiled around the beingfloizated" between the `ring` 18 and -tlie 'ofwhichtherearetwoon each side.- These platesi'will be inade ofvthin' sheet metal.

i One plate 23,on each side, is fastened Ato the ends of yt ne hub 6 and extends outwardly to about "theends of the tubeslO.' The other lisffastened to the side of the rim` andeXtends-inwardly to about the ends of ment between the hub and rim, the plates on each side working 1n contact and assisting in inaintainirig. the lateral rigidityof the wheel.

`For vehicle use the plates will preferably be omitted, `but will be used on car wheels and heavytrucks. A p C .In Figs-.j 3 and 4, modified spokes are illustrated.g They all have the tube. and plunger arrangement.' As shown in Fig: 3, the springs 19 and 20? are omitted, using only the spfriiigs 21 and 22 and in this brm @head '11 and the latter, between the ring '18 l` andjrtlie l" `flange y 15. The t parts above defscribed'ware orinay beinclosed by side plates theplungers 9, so `that 'said plates lap each l other, penmitting, however, relative move the shoulder at the yend of the tube 10 oonsists of a ring 15 secured onto the end of the tube,

springs.

scribed, `with the omission of the spring 20.

By i'nakingr the spokes as shown with telescoping sect-ions and springs ybetween and vpivotally connecting the ends of the spokes al` certain' amount of play is perinitted, wherebythehub can ield under we1ght' Aor shock, aiectingvthe notions of a spring `wheel without the use of a pneumatic ytire or. the like, and atthesame timegiving a wheel siiiiciently strong to be used on cars and fheavy. vehicles,

to cushioned wheels.

'I claim: v t l' 1. The combination with a rim and hub, of spokes pivotally connected thereto, comas indicated at 26,. whereby the ring `can be adji'lstedto vary the .tension ofthe InI Fig. et the construction is subs stantially the same as ti'iatrst above deand having the other prising slotted tubes having shoulders at thefouter ends thereof, said tubes, rings -on t tuiies connected through A the y slots to` the lplungers, and springs coiledjaround theA tubes between the vlu ngers. working-.ip a
